Katharine McPhee was one of the performers at “A Concert for Our Oceans,” which benefited Oceana — an organization that promotes ocean conservation, hosted by Seth MacFarlane at the Wallis Annenberg Center for the Performing Arts in Beverly Hills on September 28.

Joining Kristen Bell at the charity event, the 31-year-old singer and actress appeared fresh but too twee in a purple For Love & Lemons floral-printed mini dress featuring a modest high neck and long sleeves that offset the short ruffled hem and the daring cutout design at the back. Her accessories — a pair of earrings, a few rings, and a pair of maroon heels — were kept to a minimum to draw attention to her frock and shapely pins. She wore purple eye shadow to match her dress and coupled it with sheer pink lipstick and soft blush, while her brunette tresses were worn down in soft curls.
